Abstract: An electric supply terminal of an apartment house is provided to minimize a positional limit for the use of an electric implement of a user and allow the user to conveniently use electricity by supplying a commercial voltage without classifying 110V/220V. A hollow is opened in a housing(110) through an opening part formed in a front surface, and the housing(110) is buried in a wall surface so that the front surface is opened. A cover(130) covers and closes the opening part and has an insertion hole(131) and an extending hole(132). The insertion hole(131) is cut so that the 220V dedicated second plug conductive bar of a circular bar shape is closely penetrated. The extending hole(132) is extended up and down centering around the insertion hole(131) so that the 110V dedicated first plug conductive bar of a flat plate shape is closely penetrated. A moving block(150) includes the second terminal(142) and a projection(151). The second terminal(142) is faced with the tailing of the second plug conductive bar inserted into the insertion hole(131), and is electrically connected with the second wire through which 220V electricity flows. The projection(151) for covering and insulating the second terminal(142) is protruded to a front of the second terminal(142). The moving block(150) is fixed to be movable in a movement direction of the second plug conductive bar in the hollow. A supporting stand(160), located in a rear surface of the moving block(150), insulates the second terminal(142). A repulsive body elastically and repulsively supports the moving block(150) and the supporting stand(160) to the insertion hole(131). First terminals(141) are disposed to be movable up and down in a rear surface of the cover(130), and are electrically connected with a first wire through which 110V electricity flows through the first and the second conductive bodies. A holding groove with/in which the projection(151) is engaged/held is formed in a rear end of the first terminals(141). The first terminals(141) are elastically and repulsively supported through a wall surface of the hollow and a supporting spring(143). A mutual interval of a pair of the first terminals(141) is disposed to be lower than the height of the first plug conductive bar and be higher than the height of the second plug conductive bar. The first terminal(141) is electrically connected or disconnected while the first conductive body is moved by the insertion of the first plug conductive bar and is faced or separated to and from the second conductive body located in the tailing of the first wire(141). A central part of an interworking bar is fixed to be rotatable in the hollow centering around the first rotary shaft, and one end of the interworking bar is rotatably engaged with the first terminal(141). A central part of a holding bar is fixed to be rotatable in the hollow centering around the second rotary shaft. One end of the holding bar is engaged with the other end of the interworking bar, and a holding projection curved to be faced with a rear surface of the supporting stand(160) is formed in the other end of the holding bar. If the first terminals(141) are pushed from the first plug conductive bar and operate the interworking bar, the holding bar rotates by the operation so that the holding projection is separated from the supporting stand(160).
